HP Probook 450 G2
Microsoft Windows 10 (64-bit)

In my laptop (HP probook 450 G2) I've an Intel HD Graphics and after updating my windows I always get another GPU  AMD Radeon R5 m255.

 

But some days ago while updating windows I've unfortunately shut it down. After that it's showing some error like Product information not valid. Then I repair it from nearest it repairing shop. Maybe they have changed the bios. After that I noticed the system information like serial number is not the same as the back side of my laptop. 

 

Then after given a new windows I've fully update my windows but I can't find the GPU AMD Radeon R5 m255😭. I've tried many times, install some drivers but its not working. (AMD driver saying no hardware was detected.)

 

Now how can I get back this GPU. I need it badly. What should I do?
